Questions:
How many are of them?
What they make difference from the normal tenses?
In what combination of tenses are used? Ex. I (what tenses???) to doing nothing.

Ex.
perfect We wanted to have gone.
progressive I prefer doing something to doing nothing
present passive They expected to be chosen
Thanks in advance.
